Worldsell Mud Brick Kiln and Automatic Small Brick Factory Design
Raw material:Aluminum silicate glass hollow beads that are flotated from the fly ash of the heat and power plant.Low bulk density,thin wall,hollow,smooth surface,high temperature refractoriness,good insulation performance.With these of the good specifications,the high quality insulation refractory bricks can be made.
Features:high mechanical strength,low thermal conductivity,low operating temperature,better not exceed the test temperature of the re-burning line change.Energy saving,especially in the kilns of batch operation.

Property of Silica bricks for hot-blast stove
1. Under the condition of long-term high temperature and load, the volume is stable, the high temperature creep rate is low, and one or even two BF service can be used continuously.
2.600℃ above have good thermal shock resistance. Adapt to the variability of temperature of hot-blast stove, keep the bricks and masonry intact;
3. The resistance to chemical erosion is better than that of clay bricks and general high alumina bricks. The alkaline substance in the gas and soot is only limited to the surface forming a glass phase, and does not peel off the silicon brick.
4. The thermal conductivity of silica bricks is larger than that of clay bricks and high alumina bricks, which facilitates the storage and release of heat in a relatively short time.
Feactures:
1. Clay brick Good thermal stability, low thermal conductivity, good insulation performance.
2. Clay brick Low bulk density, good integrity, high mechanical strength.
3. Clay brick Good thermal shock stability, good resistance to abrasion and corrosion.
4. Good volume stability at high temperature.
5. Clay brick Low water absorption rate, low creeping rate.
6. Natural clay products, could be shaped freely, non-radioactive and environmentally friendly.
7. Clay brick Two casted method: down draft kiln and tunnel kiln. General sintering temperature: 1280-1350 °C
Application:
• Furnace construction
• Blast furnace/Hot blast stove
